eddie, i have a good feeling your snake isn't dehydrated. dehyrdation isn't something that happens one day, it's a periodic development from living in a too-dry enviornment. if your snake was dehydrated, you'd know it. bc it WOULD be soaking and WOULD be drinking, a lot.

a common sign of dehydration (and is almost ALWAYS there when a snake is dehydrated) is dented, and cracked up eyes.
